Well for months now, I have been tuning cars at 450pp for bathurst to see how well heavier cars can compare to lighter ones. I have developed some tricks to get the best performance from heavier cars and I have suprised myself at the small gap in lap times between light cars and heavier ones. Each tune was built to have a weight that is a multiple of 100kg, for example, a car that would ultimately have a min weight of say 1048kg, would get 52kg ballast so it weighs 1100kg, or 152kg ballast so it weighs 1200kg, or less weight reduction and some ballast to make it 1300kg etc. And it would get power parts/engine limiting to make it 450pp. Tunes all have comfort soft tires.
Excluding just one dominant car I tuned, here are the fastest times for tunes of different weights.
1000kg 2:30.006
1100kg 2:29.428
1200kg 2:30.303
1300kg 2:29.364
1400kg 2:30.061
1500kg 2:29.585
So all best tunes for their weight, from 1000kg to 1500kg (excluding one) are within one second of each other! That says something about the integridy of the PP system at 450PP!
Here, I will list the power to weight ratios (kg per BHP) of these tunes...
1000kg 4.46
1100kg 4.54
1200kg 4.44
1300kg 5.00
1400kg 5.28
1500kg 5.00
The excluded tune at 1000kg has 4.00 power to weight..... It doesn't handle bends super great but staight line speed is very, very good. A few other cars might also be dominant at 450pp with bogus power to weight ratios and good cornering, and you would know them from online TT's I suppose...
